SET AND LEVELER FOR THRASHING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 422,982, dated March11, 1890.

Application filed June 5, 1889. Renewed February 11, 1890. Serial No.339,999- (No model.)

To all whom it may concern:

Be it known that I, NELSON SHAFFER, a citizen of the United States,residing at Hull, in the county of Sioux and State of Iowa, haveinvented certain new and useful Improvements in Sets and Levelers forThrashing-Machines, of which the following is a specification.

In that class of thrashing-machines which are fixed or retained while inoperation upon the same trucks on which the machine is transported fromplace to place it has heretofore been necessary to stake the trucks tothe ground in order to hold them firmly in place and to excavate a placein the ground to lower the front wheels and level the machine; and theobject of this invention is to provide a set by the use of which themachine may be easily and quickly fixed in place and leveled.

The invention consists in constructions and combinations hereinafterdescribed and claimed. 7

In the accompanying drawings, which illustrate my invention, Figure 1 isa perspective of the set and leveler with the parts adjusted as in use;Fig. 2, a sectional elevation length- -wise of the device, as shown atFig. 1, and

part of a wheel; Fig. 3, a side elevation of the set and leveler and ofa thrashing-machine located thereon; Fig. 4, a top plan of the device inits folded form, as when not in use; Fig. 5, a sectional elevation inline 5 5 in Fig. 4.

Referring to the drawings by letter, the same letter indicating the samepart in the different figures, letters A represent the sides of my setand leveler with a bottom piece A fixed thereto. The side pieces A atone end are beveled off to form a seat for an incline or top a, andtheir other ends cut away to form a shoulder a and a lower part a B is aroller loosely seated on a shaft 6, which is loosely mounted in eyes 0on the ends of rods cl, the other ends of which have eyes 0, which areloosely mounted or hinged on stud-bolts 0 that project inwardly from theside pieces A.

D is a U-shaped support formed of abent rod, the ends of which areformed into eyes d, which are loosely journaled on the shaft 1).

E is a rack-bar having notches e in one of its sides and its outer endbent at a'right angle to its main portion to form a handle c. Thisrack-bar is jourualed in suitable bearings in the bottom piece A, topermit of turning it into position with the notches e at its upwardside, or at either its left-hand side or right-hand side.

Beneath the rack-bar E are fixed rodls G, which serve to support therack-bar when the thrasher is on the set and serve as fulcrum-bars for alever H. (Shown by dotted lines at Fig. 2.)

In use a set and leveler, adjusted as shown at Figs. 1 and 2, is placedwhere each hind wheel I of the thrasher-truck is intended to stand whilethe thrasher is being operated. The trucks, with the thrasher, are thendrawn forward, the hind. wheels I passing up the inclines a to theirpositions, resting a hind Wheel on the incline a and roller B of eachtruck, where they (the wheels) will be held.

in an elevated position, and also in a fixed position, thereby holdingthe thrasher in a fixed position. The hind wheels and that end of thethrasher may be adjusted in lower positions by adj ustingthe rod D inthe notches (2 toward the handle e of the rack-bar E, and

may be adjusted in more elevated positions by adjusting the rod D in anopposite direction on said rack-bar in the evident manner. A leversuchas H-may' be used with its end resting on a fulcrum-bar G to raise thebar D out of a notch e and lower it into another. The low part a of thesides A will permit inserting the lever H at oblique angles to the setwhen theset is beneath a wheel and it becomes necessary to so insertsaid lever. The roller B may be lowered by moving the bar D into theposition shown at Figs. 4 and 5, and the rack-bar E turned 011 its side,as shown at same figures, to permit shaped bar D and notched rack-bar E,substantially as and for the purpose specified.

2. In a set and leveler for portable thrashing-machines, having aninclined way a, and in combination, a roller B, carried on hingedswinging arms d, a swinging adjusting-sup port D, and a rack-bar,substantially as de scribed, and for the purpose specified.

3. In a set and leveler for portable thrashing-machines, having aninclined Way a, and in combination, a roller B, carried in swinging arms61, a swinging adjusting-support D, and journaled rack-bar E, havingnotches e and handle 6, substantially as and for the purpose specified.

4. In a set and leveler for portable thrashing-machines, and incombination, a roller B,

carried in swinging arms (1, a swinging adjusting-support D, andjournaled rack-bar E,

having notches e and handle e, substantially as and for the purposespecified.

5. In a set and leveler for portable thrashing-machines, and incombination, a roller B, carried in swinging arms cl, a swingingadjusting-support D, journaled rack-bar E, having notches e, lever H,and fulcrum-bars G, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

NELSON SHAFFER.
